STATEMAP - State Geologic Survey Mapping Component

Science Center Objects

The primary objective of the STATEMAP component of the NCGMP is to establish the geologic framework of areas that are vital to the welfare of individual States.

STATEMAP receives funds through an annual competitive grant process. Every Federal dollar awarded to a State Geological Survey is matched by a State dollar.

The primary objective of the STATEMAP component of the NCGMP is to establish the geologic framework of areas that are vital to the welfare of individual States. Each State Geologist determines the State's mapping priorities in consultation with a State Mapping Advisory Committee. These priorities are based on State requirements for geologic map information in areas of multiple-issue need or compelling single-issue need and in areas where mapping is required to solve critical Earth science problems.

Each STATEMAP project focuses on a specific area or issue. Although the individual projects last for only one year, they frequently build upon the results of previous years' mapping activities. Employees of the State Geological Surveys conduct the geologic mapping and frequently work closely with EDMAP students and their professors, as well as with FEDMAP geologists who may be mapping within the State.

STATEMAP Coordinators and Mappers Forum

On a quarterly basis, the NCGMP hosts a Forum for all STATEMAP coordinators and mappers across the nation. The intent is to provide an opportunity for open discussion, collaboration, and idea-sharing among the states. Our latest forum slides, focused primarily on Cross Sections, can be found here.

State Mapping (STATEMAP) Projects

The NCGMP is currently funding 127 projects from 45 states. These projects include both bedrock and surficial geologic mapping, and digital compilation of geologic maps.

In recent years, STATEMAP efforts have focused primarily on geologic maps that address water, aggregate, and mineral resources; and landslide and earthquake hazards. These maps are used less widely to address issues such as flooding, radon, and mine subsidence hazards; and ecosystem and wetland issues.

State Mapping (STATEMAP) Products

Each year, State Geological Surveys conduct geologic mapping with the help of both NCGMP funds (STATEMAP and State-funded efforts.

The New Mapping section of the National Geologic Map Database (NGMDB) contains information about geologic maps currently being produced for STATEMAP, as well as for FEDMAP and EDMAP.

The main Geoscience Map Catalog of the NGMDB is continuously updated to include information about published STATEMAP geologic maps and how to obtain them.


Since 1993, more than $55 million from NCGMP have supported STATEMAP geologic mapping efforts in 48 states. This amount has been matched with an equal amount from State Geological Surveys. These historical funding data may be viewed in a downloadable spreadsheet.

Funding Milestones

  • Late August-Early September: Program Announcement opens.
  • Early November: Program Announcement closes and proposals are submitted online to the USGS.
  • Early December: STATEMAP Evaluation Panel meets.
  • January: Final funding decisions are made.
  • March 15-September 15: Funds are distributed to States based on project start dates.

STATEMAP Funding Application Process

Each year in late summer, the STATEMAP Program Announcement is distributed online. Detailed instructions for submitting STATEMAP proposals can be found in the Program Announcement. It is imperative that they be precisely followed.

Applications are processed through the Web site. The State Geological Surveys have until early November to complete their project proposals and submit them online to the USGS Office of Acquisitions and Grants, where they are processed and then forwarded to the NCGMP for evaluation. Copies of the proposals are sent to the STATEMAP Evaluation Panel, which meets in early December to evaluate each proposal. Once funding levels are finalized for the current fiscal year, the Program Coordinator/s determine the amount to be allocated to each STATEMAP proposal. Funds are distributed to individual State Geological Surveys according to their project start d ates.

The actual amount of Federal funding that is available each year to the STATEMAP component is based on a formula determined by the National Geologic Mapping Act and its latest reauthorization.

Proposal Prioritization

The geologic mapping that the NCGMP funds through the STATEMAP component of the Program is determined by two processes. State Mapping Advisory Committees set the geologic mapping priorities for each State, and the STATEMAP Panel evaluates the proposed STATEMAP projects and their relation to NCGMP priorities.

State Mapping Advisory Committees

Geologic mapping priorities for each State are set with the advice of its State Mapping Advisory Committee (SMAC), which includes representatives from private industry, geotechnical consultants, Federal, State, and county officials, and academia. Current customer needs for geologic maps are considered and priorities set for mapping those areas where geologic maps are lacking or need improvement. Each State uses this information to determine the geologic mapping that will be conducted by its State Geological Survey and the projects that will be proposed to STATEMAP.

Evaluation Panel

A National STATEMAP Evaluation Panel, which has three USGS representatives and five State Geologists, meets each December to integrate State mapping priorities with NCGMP priorities and evaluate STATEMAP proposals. Each proposal is given a numerical score based on scientific and technical quality, consistency with SMAC priorities, project justification, budget, and past performance. The amount of funding is tied directly to this score.

Evaluation of Deliverables

Each project has one year from its start date to complete the project and submit the agreed-upon deliverables, although an extension of a few months may be granted. These products are examined by the Program Coordinator/s, and if the products are not received by the due date, or the quality does not meet agreed-upon terms, the State is not eligible for funding in the next proposal cycle.
